Modifications to TSI Engine for Bonneville Jetta

For the speed record attempt, specialists at THR Manufacturing in Ventura, California made modifications to the Jetta’s 2.0-liter direct-injection and turbocharged TSI engine, with new connecting rods, pistons, valves, camshafts, turbocharger, and exhaust system. These enhancements resulted in an incredible output of 600 horsepower.

“Achieving this speed at Bonneville is a demonstration of the quality, durability, power, and efficiency of the Volkswagen TSI engine series and the stability and aerodynamic efficiency of the all-new 2019 Jetta.” – Hinrich J. Woebcken, President and CEO, Volkswagen Group of America

Additional Enhancements for Bonneville Jetta

In addition to the modifications to the TSI engine, the Bonneville Jetta had many other enhancements. The suspension was lowered, special salt flat wheels and tires were fitted, and a limited-slip differential was added to aid traction. Inside the cockpit, many of the original components were removed and replaced with a roll cage, a fire suppression system, and racing seat and harness. Also, the Bonneville Jetta had a couple of parachutes installed to help slow the car down after each run.
